Nonlinear effects in the two-component medium with conductivities σ1 (metal) and σ2 (insulator) near the percolations threshold is studied. For the medium having cubic nonlinearity an effective nonlinear conductivity ae and correlation functions of the electrical field 〈e4〉 and current...

A numerical model for the vertical profile of aeolian mass flux was established based on the launch velocity probability distribution of saltating sand particles. The mean launch velocity (v̄0) was used as a primary variable in the simulation, from which the average saltation height and length...
